A Full Harvest Moon Is Set to Light Up the Sky Tonight

Kris 6 News

We’ve noticed the moon looking a little bit bigger and brighter than usual the past few nights, and tonight, it’s going to look the biggest and brightest yet. Why? Tonight there is a full moon, and this full moon is quite special.

On September 20, 2021, we will experience the 4th and final full moon of the summer. It’s often rare to have 3 full moons in one season. That’s why the third full moon of a season is considered a Blue Moon, but a fourth full moon is especially unusual.

Tonight’s full moon is known as the Harvest Moon because it is the full moon that takes places closest to the autumnal equinox. Watch the video below for more details about tonight’s Harvest Moon.


If you would like to see the full moon tonight, look outside around 7:55pm EDT. If you happen to miss it tonight, not to worry. According to NASA, it should be visible for about 3 days.

The Harvest Moon looks especially big, bright and orange due to the fact that it is located close to the horizon right around sunset. It’s all an illusion. The moon didn’t actually get bigger, but the location makes it look that way.

While you’re looking at the night sky tonight, you might also be able to see the planet Mercury. According to NASA, around 7:38pm EDT, Mercury will be about 2 degrees above the horizon if you look towards the west-southwest.

Are you going to look for the Harvest Moon tonight? Are you going to look for Mercury too?
